This document defines terms, gives guidance for classification and establishes requirements for nucleic acid- and protein-based bio-devices. This document is applicable to bio-devices incorporating natural, modified and synthetically derived nucleic acid and/or protein. This document does not apply to medical devices or products.

 

This part of ISO 8502 describes a method of extracting and analysing of water-soluble contaminants from a surface by use of filter paper which can be attached to any surface, regardless of its shape (flat or curved) and its orientation (facing in any direction, including downwards). The method described is suitable for use in the field to determine the presence of water-soluble contaminants before painting or a similar treatment. NOTE The extraction method can give a false conductivity result or not take all the water-soluble material off the surface because of: (1) Soluble materials hiding in the crevices or under folds of metal; (2) Soluble materials under corrosion layers, passivation layers produced by corrosion inhibitors, oil, grease, or other non-visible thin films.

 

 

This document specifies requirements for utility lighters to ensure a reasonable degree of safety for normal use or reasonably foreseeable misuse of such lighters by users. This document applies to all flame-producing consumer products commonly known as utility lighters (also known as grill lighters, fireplace lighters, lighting rods or gas matches), and similar devices. It does not apply to matches and flame-producing products intended for igniting cigars, pipes and cigarettes.

 

This document specifies a method of determination of the sieve residue (gross particle and coagulum content) of polymer dispersions. This document is only applicable to coagulum type content.

 

This document specifies requirements for high chromium white cast iron grit, as supplied for blast-cleaning processes. It specifies ranges of particle sizes, together with corresponding grade designations. Values are specified for hardness, density, defect/structural requirements, metallographic structure and chemical composition. The requirements specified in this document apply to abrasives supplied in the new condition only. They do not apply to abrasives either during or after use. High chromium white cast iron grits are used in both static and site blasting equipment. They are most often selected where there is a possibility for the recovery and re-use of the abrasive. NOTE 1 Although this document has been developed for preparation of steelwork, these materials are predominantly used for non-ferrous substrates. The properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques, and can be used for applications where no subsequent coating is applied. NOTE 2 Whenever dissimilar metals are used together, galvanic corrosion can occur.

 

This document specifies requirements for lighters to ensure a reasonable degree of safety for normal use or reasonably foreseeable misuse of such lighters by users. This document applies to all flame-producing products commonly known as cigarette lighters, cigar lighters and pipe lighters. It does not apply to matches and flame-producing products intended solely for igniting materials other than cigarettes, cigars, and pipes.

 

This document specifies the principal specifications of the thermoplastic water meter cabinets in terms of  the thickness of material, design drawing, dimensions and accessories incorporated into the construction of it for pipe sizes from 1/2” to 1 1/4” (from 12,7mm to 31,75 mm).

 

This document specifies a method for the extraction of phosphorus soluble in mineral acids in inorganic fertilizers.

 

This document specifies a method for the extraction of the total sulfur contained in fertilizers in elemental form and/or in other chemical combinations. The method is applicable to inorganic fertilizers for which a declaration of the total sulfur present in various forms (elemental, thiosulfate, sulfite, sulfate) is provided.

 

This document specifies a method applicable to inorganic fertilizers for the extraction with diluted mineral acid of total calcium, total magnesium and total sodium and for the extraction of total sulfur present in the form of sulfates, so that the same extract may be used for the determination of each nutrient required.

 

This document specifies a method for the extraction of water-soluble calcium, magnesium, sodium and sulfur (in the form of sulfates), so that the same extract can be used for the determination of each nutrient required. This document is applicable to inorganic fertilizers.

 

This document lists the best available acute-toxicity data of gases taken from a search of the current literature to allow the classification of gases and gas mixtures for toxicity by inhalation.

 

This document specifies requirements of rubber hoses used in the automotive turbocharger system to connect turbocharger, intercooler, and internal combustion engine at the working temperatures from -40 °C to +250 °C and the working pressures from -0,01 MPa(-0,1 bar) to 0,5 MPa(5 bar). Hoses covered by this document are straight or shaped.

 

 

ISO 10298:2018 lists the best available acute-toxicity data of gases taken from a search of the current literature to allow the classification of gases and gas mixtures for toxicity by inhalation.

 

This document specifies a method for the determination of the bio-based carbon content in products, based on the 14C content measurement. This document also specifies three test methods to be used for the determination of the 14C content from which the bio-based carbon content is calculated: — method A: Liquid scintillation-counter (LSC); — method B: Accelerator mass spectrometry (AMS); and — method C: Saturated-absorption cavity ring-down (SCAR) spectroscopy. The bio-based carbon content is expressed by a fraction of sample mass or as a fraction of the total carbon content. This calculation method is applicable to any product containing carbon, including bio-composites. NOTE This document does not provide the methodology for the calculation of the biomass content of a sample, see EN 16785 1 and EN 16785 2.

 

This document specifies a method for the extraction of phosphorus soluble in neutral ammonium citrate in inorganic fertilizers.

 

This document specifies the procedure for extraction of different organic and organo-mineral fertilizers with water to enable a subsequent determination of boron (B), cobalt (Co), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), phosphorous (P) and zinc (Zn). NOTE Extracts prepared by the procedure given in this document can also be applied for determination of other elements. This document is applicable to the fertilizing products blends where a blend is a mix of at least two of the following components: fertilizers, liming materials, soil improvers, growing media, inhibitors, plant biostimulants, and where the following category: organic fertilizers, organo-mineral fertilizers is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If the organic fertilizer or the organo-mineral fertilizer is not the highest % in the blend, the European Standard for the highest % of the blend applies. In case a fertilizing product blend is composed of components in equal quantity, the user decides which standard to apply. Variations in analytical methods for fertilizing product blends can lead to differing results as some components or matrix interactions can affect the outcome. Validation procedures have shown that developed standard methods are robust and reliable across diverse product compositions, but possible interferences and unexpected results when analysing fertilizing product blends are possible.

 

ISO 8501-1:2007 is a hardback A5-format book in four languages (English, French, German and Swedish), which specifies a series of rust grades and preparation grades of steel surfaces. The various grades are defined by written descriptions together with photographs that are representative examples within the tolerance for each grade as described in words. It is applicable to hot-rolled steel surfaces prepared for painting by methods such as blast-cleaning, hand and power tool cleaning and flame cleaning, although these methods rarely lead to comparable results. Essentially, these methods are intended for hot-rolled steel, but blast-cleaning methods, in particular, could also be used on cold-rolled steel of sufficient thickness to withstand any deformation caused by the impact of the abrasive or the effects of power tool cleaning. This part of ISO 8501 is applicable also to steel substrates that show residues of firmly adhering paint and other foreign matter in addition to residual mill scale.
